I bought these replacement cheek pads to custom fit my HJC IS-MAX snowmobile helmet. According to the size chart I needed a small helmet. The small fit kind of tight especially in the cheekbone area. It was bothering me enough to look into it. An HJC rep suggested I swap the small cheek pads for a size medium. It is still a tight fit but it no longer bothers me. I am sure that the padding will pack out a little more this season and this helmet will become a perfect fit. Thanks Dennis Kirk for having this part available and at a great price. I was very impressed with your ordering and shipping system. I have told several of my snowmobile buddies to check you guys out first before buying parts and accessories. Thanks again!
